Preheat oven to 450 degrees -- with pizza tray/stone inside oven. Let tray/stone get hot for about 15 to 20 minutes. In the meantime, prepare your dough on the counter. Today, I put sesame seeds on the bottom of the dough.
Steam broccoli for 2 minutes, then place into saute pan with onion, peppers, mushrooms, and garlic. Saute for about 4-5 minutes on medium heat.
Spread the 2 tbs of olive oil on top of your dough and place onto hot pizza tray/stone. Bake the dough for 9 minutes in the oven then take it out.
Spread layer of cheddar cheese on partially baked dough, then your veggie mixture, then a layer of mozzarella cheese. Add parmesan cheese and red pepper flakes as well.
Bake in the oven for another 9-11 minutes, or until desired crispiness.
